The Mossel Bay DMR Repeater is back on the air after comprehensive structural upgrades and modifications. The cooling issue was solved by adding a second fan to the transmitter of the repeater. This fan runs continuously and will keep the transmitter cool. The second fan also for the transmitter will start when the temperature reach more than 50 Degrees Celsius and will increase in speed as the temperature rises. I am sure this will keep the transmitter cool even on the hottest of days.
Higher rubber feet (4) was added to the bottom of the repeater to allow for better airflow in the repeater cabinet. I also added two aluminum carry handles. But why carry handles? In the shack the handles come in handy if you want to work on the repeater of move it to another area of the shack. The repeater was constructed to be installed in a 19 inch rack but in its current location there is no space for a 19 inch rack.
I have a few other minor alterations that I would like to make in the future. More on this in a future article.
